Many (read/write?) errors during Junos OS update

  • 1.  Many (read/write?) errors during Junos OS update

    Posted 11-27-2018 02:44

    Hi there,

     

    we just updated Junos OS to version 15.1R7.9. On two virtual chassis everything went fine. On the third one we saw a lot of errors during the process indicating disk problems. The messages often contains some output like

    UNEXPECTED SOFT UPDATE INCONSISTENCY

    It seems that the switch(es) autocorrect all the errors, and we ended up with a working and updated virtual chassis.

    Nevertheless we have "mixed feelings" about this. So I like to know what we can do to check the storage hardware.

    We did

    root@ourswitch:RE:0% nand-mediack
    Media check on da0 on ex platform

    the output looks good, doesn't it? Does it check the media on all switches of the virtual chassis?

    What do you suggest we should do/check?

     

    Thanks for your support and many greets
    Stephan

     

    edit: I forgot to mention that this is about EX3300-Switches.

    Hi there,

     

    When you ran the command "nand-mediack", did you see any output? 

    If you din't see any it means that there were no bad blocks observed.

     

    Had there been any, you would see the o/p like the below:

    groza_lab@ex:RE:0% nand-mediack
    Media check on da0 on non-srx platforms
    Zone 02 Block 0172 Addr 08ac00 : Bad erase
    Recovering block
    Zone 07 Block 0520 Addr 1e0800 : Bad erase
    Recovering block
    Zone 07 Block 0631 Addr 1e7700 : Bad erase
    Recovering block
    Zone 08 Block 0856 Addr 235800 : Bad erase
    Recovering block

     

    You can check the boot-logs if there are any messages concerning the bad blocks or file system, if it is clean then there is nothing to worry upon...

     

    Kudos are appreciated! 🙂

    And yes - nand-mediack have no output, so I think it's fine, too.

    Thanks a lot for your support and many greets
